Bone morphogenetic protein-2 (BMP-2) is expected to be utilized to fill bone defects and promote healing of fractures. However, it is unable to generate an adequate clinical response for use in bone regeneration. Recently, it was reported that glycosaminoglycans, including heparin, heparan sulfate, keratan sulfate, dermatan sulfate, chondroitin-4-sulfate, chondroitin-6-sulfate, and hyaluronic acid (HA), regulate BMP-2 activity, though the mechanism by which HA regulates osteogenic activities has not been fully elucidated. The aim of this study was to investigate the effects of HA on osteoblast differentiation induced by BMP-2.Monolayer cultures of osteoblastic lineage MG63 cells were incubated with BMP-2 and HA for various time periods. To determine osteoblastic differentiation, alkaline phosphatase (ALP) activity in the cell lysates was quantified. Phosphorylation of Smad 1/5/8, p38, and ERK proteins was determined by Western blot analysis. To elucidate the nuclear translocation of phosphorylated Smad 1/5/8, stimulated cells were subjected to immunofluorescence microscopy. To further elucidate the role of HA in enhancement of BMP-2-induced Smad signaling, mRNA expressions of the BMP-2 receptor antagonists noggin and follistatin were detected using real-time RT-PCR.BMP-2-induced ALP activation, Smad 1/5/8 phosphorylation, and nuclear translocation were up-regulated when MG63 cells were cultured with both BMP-2 and HA. Western blot analysis revealed that phosphorylation of ERK protein was diminished by HA. Furthermore, the mRNA expressions of noggin and follistatin induced by BMP-2 were preferentially blocked by HA.These results indicate that HA enhanced BMP-2 induces osteoblastic differentiation in MG63 cells via down-regulation of BMP-2 antagonists and ERK phosphorylation.

骨形态发生蛋白2（BMP-2）有望用来填充骨缺损并促进裂缝的愈合。但是，它无法产生足够的临床反应以用于骨再生。最近，据报道，包括肝素，硫酸乙酰肝素，硫酸肝素，硫酸盐，硫酸皮肤菌，软骨素-4-硫酸盐，硫酸软骨蛋白-4-硫酸盐，6-硫酸软骨蛋白-6-硫酸盐和软骨酸（HA），透明质酸（HA），尽管Elucitiiss的机械性均未进行机械性，而Haegulates Incogenisis Incogenical sogeniciss ost ost oste，包括肝素，硫酸乙酸乙酰胺，硫酸盐，硫酸盐，硫酸盐。这项研究的目的是研究HA对BMP-2诱导的成骨细胞分化的作用。将成骨细胞谱系MG63细胞的单层培养物与BMP-2和HA孵育不同。为了确定成骨细胞分化，定量细胞裂解物中的碱性磷酸酶（ALP）活性。 SMAD 1/5/8，P38和ERK蛋白的磷酸化通过Western印迹分析确定。为了阐明磷酸化SMAD的核易位1/5/8，刺激的细胞进行免疫荧光显微镜。为了进一步阐明HA在增强BMP-2诱导的SMAD信号传导中的作用，使用实时RT-PCR.BMP-2诱导的ALP激活，BMP-2受体拮抗剂Noggin和Follistatin的mRNA表达，SMAD 1/5/8 PhosphoryLation和核转运在Mg63细胞上均与HA BRM时，SMAD 1/5/8 phosploration corportation smad 1/5/8 phosperation诱导的ALP激活。 Western印迹分析表明，HA会减少ERK蛋白的磷酸化。此外，BMP-2诱导的Noggin和Follistatin的mRNA表达优先通过HA来阻止。这些结果表明，HA增强的BMP-2通过下调BMP-2拮抗剂和ERK磷酸化而诱导MG63细胞中成骨细胞分化。
